· For some of the candidate systems the necessary technical planning parameters are not fully available thus making it difficult to perform a systematic comparative technical analysis at this point in time.· A supplementary Report (to this Report) will be required to provide the technical elements and parameters needed for the introduction of digital systems in Band II.· There are issues with spectral bandwidth of some candidate systems relative to the planning provisions of GE84 which will make their use problematic in Band II which is heavily occupied by existing services, and which could necessitate re-planning if these systems were to be widely deployed.· Administrations do not wish to have another major planning conference to replace the GE84 Agreement for new digital services.· Administrations do not wish to lose their existing rights under the GE84 Plan. Consequently, there is a need for any incoming system to comply with the provisions of GE84 Agreement.· There may be program and technical licensing issues on a national basis. For example, an FM program licence may have been granted following an open competitive tender process for an individual single service, and any subsequent changes which would enable a multiplex capability to such an existing licensee could be problematic.
Saving the Neglected History of FM Radio’s Unsung PioneerBy JOSEPH PLAMBECKPublished: April 18, 2010The questions seemed simple enough: When and how did Edwin H. Armstrong, the father of FM radio, make the discovery that led to that invention?In 2007, Mischa Schwartz, an emeritus professor of electrical engineering at Columbia, tried to find the answer. He starting digging into some of the nearly 600 boxes of Armstrong’s archives donated to Columbia decades ago, only to find them disorganized and his quest complicated.He also saw the condition of the archives as a deterrent to other scholars who might be interested in Armstrong, a figure who largely fell out of public awareness — his name “sliding toward oblivion,” The New York Times wrote in 1981 — just decades after he committed suicide in 1954.Even Mr. Schwartz, who considers Armstrong the “greatest inventor in radio,” admitted to giving Armstrong short shrift in the past. In textbooks that he had written, Mr. Schwartz said he had attributed advancements to one inventor, only to later discover that Armstrong had made the same discovery and had understood it much better.So Mr. Schwartz reached out to groups like the Institute of Electrical and Electronics Engineers Foundation and raised more than $70,000 to get an archivist at Columbia, Jennifer Comins, to organize the material.The collection includes papers outlining his theories; photographs of Armstrong and his many inventions; to-do checklists; reel-to-reel audio; and boxes of material from the many years of litigation between Armstrong and RCA, and Armstrong and Lee De Forest, another inventor, over patent issues.Ms. Comins, who has the help of a graduate student, Jennifer Howard, began the project last December and plans to finish by the end of November. They created a blog that would track their findings and, they hoped, renew some interest in Armstrong.“When I was growing up I heard about Edison and Marconi, and I never heard of him,” said Ms. Comins, 37. “And now I wonder why.”
